The Last Hope

"Zhao Yu, do you remember last time when we solved the bank case?" Miao Ying asked.

"Huh? Why do you want to bring that up?" Zhao Yu asked, curious.

Miao Ying recalled the case. "This is what I am thinking about. The biggest difficulty in the bank case was figuring out how the murderer did it. Because we couldn't find anything in common between the murders, we didn't make much progress in the case for a long time," she said.

Zhao Yu nodded. "Yes, but later when we turned our attention to the tunnel accident, the real murderer suddenly came to the surface. Meow, you mean...?"

"Apart from helping the Secret Service look for the treasure, do the five experts have anything else in common?" Miao Ying asked.
